Reference to non-existent field 'D1t'.

hi there,

I need to run the file "Integration" I found in the web.

the input parameters are:

N: 54000

Pin: 100000

T: 303.3500

Vp: 0.0250

At: 0.0033

I just keep getting after I put all the necessary input.

I really can't find the solution.

PAR.Ac = (pi/4)*((PAR.D1t^2)-(PAR.D1h^2)); %Compressor area

There's no information for your PAR.D1t and PAR.D1h. I guess these are diameters. Consider adding these:

PAR.D1t = input ('Insert outer diameter (m) ' )
PAR.D1h = input ('Insert inner diameter (m) ')
